Hilary of Poitiers

Or, the servant to whom two talents were committed is the people of the Gentiles justified by the faith and confession of the Son and of the Father, confessing our Lord Jesus Christ, to be both God and Man, both Spirit and Flesh. These are the two talents committed to this servant. But as the Jewish people doubled by its belief in the Gospel every Sacrament which it had learned in the Law, (i. e. its five talents,) so this people by its use of its two talents merited understanding and working.

Thomas Aquinas

And he also that had received the two talents came: above the judgment with regard to the first servant, who had received five talents, was treated; here the judgment with regard to the second servant, who had received two talents, is treated. As to the letter it differs in nothing from the first, nor is there anything to be said beyond what was said of the first; and therefore it is not necessary to repeat, because this one also received the same commendation and the same reward as the one who had received five talents.
